There have been more than 40 U.S. presidents since the country's founding in 1776, and, like the rest of us, they all had their own food preferences. American cuisine has changed quite a bit over the past two and a half centuries, so it's hardly surprising that George Washington's diet wasn't exactly in lockstep with John F. Kennedy's or Bill Clinton's. Many Americans today are unfamiliar with hoecakes, for instance, a breakfast item the first commander-in-chief was especially fond of.
